==''Torulaspora delbrueckii'' habitats==
The genetic analyses have revealed that the various [[Strain (biology)|strains]] treated as ''T. delbrueckii'' actually represent different species (and belong even to different genera, like ''[[Debaryomyces]]'', ''[[Saccharomyces]]'' and ''[[Candida (genus)|Candida]]''). Thus, the criteria of the species ''T. delbrueckii'' apparently needed some revision according to the type strain (the strain SANK 50118).
''T. delbrueckii'' is isolated from several human [[bioprocess]]es, including the bread industry <ref>{{cite journal | author = Pacheco A., Santos J., Chaves S., Almeida J., Leao C., Sousa M.J. | title = The Emerging Role of the Yeast Torulaspora delbrueckii in Bread and Wine Production: Using Genetic Manipulation to Study Molecular Basis of Physiological Responses | journal = Structure and Function of Food Engineering | volume = | issue = | pages = | year = 2012 | month = | pmid = | doi = </ref><ref>journal | author = Hernandez-Lopez M.

Torulaspora delbrueckii is a ubiquitous yeast species with both wild and anthropic habitats. The type strain of T. delbrueckii is CBS 1146T, equivalent to CLIB 230 or ATCC 10662, etc.. The type strain of T. delbrueckii CBS 1146 T was recently sequenced [1], and is composed of 8 chromosomes in addition to a mitochondrial genome. T. delbrueckii was formerly known as Saccharomyces delbrueckii or Saccharomyces rosei or Saccharomyces roseus, and the anamorph is called Candida colliculosa (for a complete list of synonyms, see CBS's website). T. delbrueckii is the most studied species of the Torulaspora genus that comprised 8 species to date, of which T. franciscae, T. pretoriensis, T. microellipsoides, Torulaspora globosa, T. indica [2], T. maleeae [3], and T. quercuum [4]. The taxonomy of the Torulaspora genus is evolving rapidly, and the availability of molecular tools to discriminate Torulaspora species [5] will help correcting errors in species assignments.

Torulaspora delbrueckii habitats

T. delbrueckii is isolated from several human bioprocesses, including the bread industry [6][7][8][9][10] where some T. delbrueckii strains are commercialized for frozen dough applications [11]. Other applications include food fermentations of silage, cocoa [12][13], olive [14] or cucumber [15][16]; distilled and traditional fermented beverage production including mescal [17], colonche [18], tequila [19], cider [20], strawberry tree fruits juice [21], sugarcane juice [22][23] or kefir [24]; dairy products’ fermentations like traditional cheeses [25] and fermented milk [26]. T. delbrueckii can be an opportunistic spoilage yeast for dairy products or soft drinks (fruit juices, etc.) [27][28][29]. T.delbrueckii colonizes several natural environments, ranging from soils [30], to plants [31], fruits [32] and insects [33][34]. T.delbrueckii is occasionally found as a clinical isolate, although not considered to be a human pathogen [35], a state described as opportunistic pathogen.

Torulaspora delbrueckii and winemaking

T. delbrueckii has been associated with winemaking for decades [36][37][38] and isolated either from grape, must or wine. T. delbrueckii is now proposed as starter culture (to be associated with S. cerevisiae in mixed cultures) for certain applications, particularly to reduce volatile acidity in high-sugar fermentations like in Sauternes wines [39]. Recent findings show that T. delbrueckii species has been domesticated for winemaking and other human uses about 1900 and 4000 years ago respectively [40].

Torulaspora delbrueckii life-cycle

The life-cycle of T. delbrueckii remains unclear. Some authors consider T. delbrueckii to be a haploid species, while more recent findings suggest T. delbrueckii have a mostly diploid homothallic life[41]. To date, the life-cycle of the species is not formally elucidated.
